350 Brake Booster
Just finished upgrading my 89' brake booster and master cylinder to the F350 setup. Everything went smoothly. I've searched, but come up with different opinions about optimum vacuum to make this larger booster perform at its best. At warm idle right now my gauge on the booster vac line is reading 18 in-Hg. Will this suffice? Engine is 351W, all stock except for headers and all smog removed. Thanks in advance for the responses!
